である。 First, to explain the pump automatic operation device that is the subject of the present invention, in FIG. 1, 1 is a resistance valve interposed in the pump discharge pipe 2, 3 is a differential pressure diaphragm that responds to the pressure difference across the resistance valve, and 4 is a A pressure receiving diaphragm that responds to the pressure of the discharge pipe; 5 a reed switch connected to the pressure diaphragm 4 via a rod 6 and a reversing lever 7; 8 a magnet held by the differential pressure diaphragm 3 to control opening and closing of the reed switch 5. In FIG. 2, 9 is a relay whose excitation is controlled by the reed switch 5, and 10 is a relay contact inserted into the power supply circuit of the pump motor 11.

ている。 When the pump is stopped, the pressure receiving diaphragm 4 is moved upward by the pressure within the discharge pipe, and the reversing lever 7 is reversed downward so that the reed switch 5 at its free end is in the downward position. On the other hand, the differential pressure diaphragm 3 is moved upward by the biasing force of the spring because the pressure difference between the front and rear of the resistance valve 1 is P 1 -P 2 =0. Therefore, magnet 8
approaches reed switch 5 and turns it off,
When the relay 9 is de-energized, the relay contact 10 is opened.

ツト８から遠ざかつてONとなり、ポンプは運転
を開始する。 When the water faucet is opened, the pressure in the discharge pipe decreases, causing the pressure receiving diaphragm 4 to move downward, and as the reversing lever 7 is reversed upward, the reed switch 5 moves away from the magnet 8 and turns on, and the pump starts operating.
流量大なる場合、P1≫P2のため、差圧ダイヤ

している。 When the flow rate is large, since P 1 >>P 2 , the differential pressure diaphragm 3 moves downward against the spring, so the reed switch 5 stably maintains the ON state.

るに至らずポンプは尚運転を続ける。 When the flow rate is small when the faucet is closed, the pressure receiving diaphragm 4 moves upward due to the increase in the internal pressure of the discharge pipe, and the reed switch 5 is reversed downward, but due to the pressure difference P 1 - P 2 at that point, the differential pressure diaphragm 4 3 remains in the depressed state, and therefore the pump continues to operate without the magnet 8 turning off the reed switch 5.

によりターンOFFしてポンプの運転を停止させ
る。 When the faucet is closed, the differential pressure diaphragm 3 moves upward, and the reed switch 5 is turned off by the proximity of the magnet 8, stopping the operation of the pump.

である。 As described above, according to the present invention, when a magnet is attached to a differential pressure diaphragm in a differential pressure detection section of an automatic pump operation device, the magnet can be connected to a reed switch using the mounting seat into which the magnet fits and the protrusion that indicates the magnet polarity direction. It is now possible to incorporate the reed switch into the differential pressure diaphragm with the normal rotational angular positional relationship between the magnet and the pressure receiving diaphragm. The operation of the pump can be reliably controlled through movement, making it practical as an automatic pump with a smaller pressure tank.
